Application January 26,

16 Claims.

The present invention relates to heddle frames, and aims to provide aheddle frame so constructed that excess heddles may be readily'removedor additional heddles added, with the warp ends intact, when it isdesired to vary the construction of the goods being woven.

An important object of the invention is to provide a heddle frame ofthis character wherein the end bars thereof may be swung laterally andthe heddles removed or replaced, the end bars being so constructed thatthe frame will be held against collapsing while the heddles are beingchanged.

With the foregoing and other objects in View, which will appear as thedescription proceeds, the invention, resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed,

may be made within the scope of what is claimed, without departing fromthe spirit of the invention.

Referring to the drawings:

Figure 1 is a iragmental elevational view of a heddle frame constructedin accordance with the invention.

Figure 2 is an end elevational view thereof.

Figure 3 is a iragmental elevational view illustrating the end bar ofthe heddle released to be moved laterally for the removal of theheddles.

Figure l is a sectional view taken approximately on line 4- 1 of FigureFigure 5 is a iragmental view illustrating the position of the end barwhen it has been moved laterally.

Referring to the drawings in'detail, the reference character 5designates the upper and lower bars of the heddle frame, which aresupplied with the usual heddle bar securing members 6, to which theheddle bars '7 are connected. The heddle bars 7 are disposed in parallelspaced relation with the bars 5 of the heddle bar frame, the heddle bars7 supporting the steel heddles 8, in the usual and well known manner.

The bars 5 of the heddle frame are held in spaced relation with eachother, by means of the metallic end pieces 9, which have inwardlyextended ends 10 that rest against the inner edges of the bars 5, asclearly shown by Figure 1 of the drawings.

The ends 10 are formed with elongated openings 11 that accommodate thebolts 12 that extend through the bars 5 to pivotally connect the endpieces 9 to the bars 5, the elongated openings 11 1932. Serial No.588,975

permitting of sliding movement of the end pieces 9 with respect to thebars 5.

Notches 13 are formed in the ends 10, and are designed to accommodatethe lugs 14 that form a part of the fittings 15, so that when the endpieces are moved to their active positions, twisting of the end pieceswill be prevented.

The end pieces 9 are also formed with openings through which the ends ofthe heddle bars lextend, the heddle bars being formed with openings toreceive the members 16 that are carried by the end pieces 9, so that theheddle bars are securely held against movement, with respect to the endpieces 9.

These members 16 embody lengths of spring wire material, which arelocked in position on the end pieces, the right angled ends of themembers 16 being extended through openings in the heddle bars.

Should it be desired to remove or position a number of steel heddles, itis only necessary to loosen the nuts on the bolts 12 loosening the endpieces 9.

The members 16 are now moved to disengage the heddle bars 7 so that theend pieces 9 may be moved laterally to disengage the heddle bars '7.With the end pieces in this position, or in a position as shown byFigure 3 of the drawings, the end pieces are swung rearwardly to aposition as shown by Figure 5 of the drawings, leaving the ends of theheddle bars free so that the heddles may be slid over the ends of theheddle bars.

Due to the construction shown and described, it will be seenthat duringthe changing of the heddles, the end pieces hold the bars of the heddleframe in proper spaced relation with each other and prevent collapsingof the frame.

After the adjustment of the heddles has been made, the end pieces 16 arereturned to their active positions and the nuts of the bolts 12 aretightened, securing the end pieces against displacement.

Having thus described the invention what is claimed is.

1. A heddle frame comprising upper and lower bars, pivoted end bars forholding the upper and lower bars in spaced relation with each other,heddle bars supported by the upper and lower bars, said end bars havingopenings to receive the ends of the heddle bars to removably mount theheddle bars on the end bars, and means for securing the heddle barsagainst movement.

2. A heddle frame comprising main bars, end bars pivotally connectedwith the main bars for holding the main bars in spaced relation witheach other, heddle bars supported by the end bars, and heddles mountedon the heddle bars.

3. A heddle frame comprising main bars, end bars pivotally mounted onthe main bars and adapted to swing laterally, said end bars havingopenings, heddle bars supported by the main bars, the ends of the heddlebars extending through the openings, means carried by the end bars andengaging the heddle bars for securing the heddle bars against movement,and heddles mounted on the heddle bars.

4. In a heddle frame, main bars, end members having right angled ends,bolts extending through the right angled ends and the main bars forpivotally connecting the end bars to the main bars, heddle bars, andmeans for detachably connecting the heddle bars to the and bars.

5. In a heddle frame, main bars, end bars connecting the main bars forholding the main bars in spaced relation, heddlc bars, the ends of theheddle bars extending through the end bars, heddles on the heddle bars,said end bars being movable laterally out of the path of travel ofheddles being removed from the heddle bars, and means for securing theheddle bars against movement.

6. In a heddle frame, main bars, end bars pivotally connectedwith themain cars and adapted to swing laterally of the main bars, and heddlebars removably connected with the end bars.

'7. In a heddle frame, main bars, and bars pivotally connected with themain bars, said end bars having openings, heddle bars, the ends of theheddle bars extending into the openings, and securing members mounted onthe end bars for engaging the heddle bars to removably secure the heddlebars in position.

8. In a heddle frame, main bars, end bars pivotally connected withthemain bars, means for restricting pivotal movement of the end barswith respect to the main bars, heddle bars removably connected with theend bars, and heddles mounted on the heddle bars.

9. In a heddle frame, main bars, pivoted end bars secured to the mainbars for holding the main bars in spaced relation, heddle bars, heddleson the heddle bars, means for rcmovably connecting the heddle bars tothe end bars, whereby the heddles mounted on the heddle bars, may beremoved.

10. In a heddle frame, main bars, end bars having right angled endportions formed with elongated openings, bolts passing through theopenings and main bars to secure the end bars in position on the mainbars, means for preventing pivotal movement of the end bars under normalconditions, and heddle bars removably connected with the end bars.
